本文提出了一种新的数值方法，用于改进水平集方法在流场中界面被动平流时的质量守恒性质。我们的方法使用拉格朗日标记粒子来重建分辨率不足区域的水平集。对于经历拉伸和撕裂的流动，情况往往如此。整体方法保持了光滑的几何描述的接口和水平集方法的实现简单的特点。我们的方法相比毫不逊色，体积的流体方法在质量守恒和纯拉格朗日计划的接口分辨率。该方法是在三个空间维度。(C)2002 Elsevier Science（美国）。
In this paper, we propose a new numerical method for improving the mass conservation properties of the level set method when the interface is passively advected in a flow field. Our method uses Lagrangian marker particles to rebuild the level set in regions which are underresolved. This is often the case for flows undergoing stretching and tearing. The overall method maintains a smooth geometrical description of the interface and the implementation simplicity characteristic of the level set method. Our method compares favorably with volume of fluid methods in the conservation of mass and purely Lagrangian schemes for interface resolution. The method is presented in three spatial dimensions.
